Acer Veriton N4670g vs. Lenovo ThinkCentre M900 Small
Comparison and Differences
Differences between Acer Veriton N4670g and Lenovo ThinkCentre M900 Small
If you are looking for a more modern desktop, then you should go with the Acer Veriton N4670g which was released in 2020. The Lenovo ThinkCentre M900 Small is older and entered production in 2015.
If you are looking for the smaller form factor the Acer Veriton N4670g is the right one for you. It is smaller than the Lenovo ThinkCentre M900 Small and will fit more easily under your desk.
Processor
Usually the newer the generation of the CPU, the better the performance and efficiency is. If your budget allows it, you should go with the Acer Veriton N4670g as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M900 Small is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Lenovo ThinkCentre M900 Small has 4 RAM slots while the Acer Veriton N4670g has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.
The Acer Veriton N4670g is using the faster 2933 MT/s RAM. The Lenovo ThinkCentre M900 Small is slower by supporting RAM speeds of up to 2133 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Lenovo ThinkCentre M900 Small as it has the ability to run 64 GB of RAM. The Acer Veriton N4670g can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Lenovo ThinkCentre M900 Small has 8 USB ports. The Acer Veriton N4670g is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the Acer Veriton N4670g, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Lenovo ThinkCentre M900 Small has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Lenovo ThinkCentre M900 Small comes with 2 ports, while the Acer Veriton N4670g has only 1. If you are planning to use multiple monitors, the Lenovo ThinkCentre M900 Small is the better choice.
The Acer Veriton N4670g comes with an HDMI port, while the Lenovo ThinkCentre M900 Small does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the Lenovo ThinkCentre M900 Small is better equipped as it comes with 3 SATA slot(s), while the Acer Veriton N4670g has 1 slot(s).
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Acer Veriton N4670g. Sadly, the Lenovo ThinkCentre M900 Small has no such slot, and you will be forced to use the SATA interface instead.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Acer Veriton N4670g comes with a decent 90 Watt PSU, but the Lenovo ThinkCentre M900 Small has a more powerful one rated at 210 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
